MOUNTING LAMP-SKADES.

To all whom it may concern.

Be it known that I, SAMUEL ROBERT SCHWARTZ, a citizen of the UnitedStates of America, residing at New York, in the county of New York andState of New York, have invented a new and useful Improvementin MountingLamp-Shades, of which the following is a specification.

This inventionlrelates to improvements in mounting lamp shades and hasfor its main object the provision of a simple and attractive structurewhich will enable ready mounting andremoval of a lamp shade withoutinterfering 1 withfthe: illuminating qualities of the lamp. f

Other and further -objects will appear from the following specification,taken in conjunction with the drawings, in which:

Figure l is a perspective View of an electric desk lamp, and shows myinvention appliedthereto.

:Fig. 2 is a detail view of theshade of the lamp shown in Fig. 1 and ofmy invention applied thereto.

Fig. 3 is'a View of'one end of the shade,

similar to the view of Fig. 2.

Fig. a is'a View of the end of the shade opposite to th e'one' shown inFig. 3.

Fig. 5 is a sectional 'view taken on the line 5-5 of Fig. the directionof the arrows. I

Fig. 6 is'a 'det invention.

Fig. 7 is a view of a modified form of shaide which may be used with myinvention, an a 5 Fig 8 is a view showing a modification of my inventionapplied to the shade shown in ail view of apart of my Fig.

' In-Fig.'1 is shown a portable electric desk lamp ofwell' knowntype,consisti ng of a shade A pivotally supported at two points on atubular supporting bracket B, and a swivel joint D'connecting thebracket with the base E; The bracket B carries an incandescent lampsocket F of standard type, which carries 'thelamp G. V (See Fig. 5.)Through the "tubular bracket B passes electric wiring H whichconnectsthe lamp socket F with the source of current.

So far I have described a well-known construction.

providedwith a bushing 2, which is the cus topiary form of constructionfor modern 'My' invention will next be. described'in detail. The lampsocket F is Specification of Iietters latent. Patented Au g go 1921,Application filed November 24, 1920. Serial No. 426,148.

lamp sockets. In one end of the shade A a slot 1 is provided, the end ofwhich is rounded so as to provide a seat forthe bushing 2,

thus providing a pivotal bearing-when the bushing is slid into the slot.The shade is further provided with a projecting rim 3.

In order to hold the shade A inpivotal engagement with the bushing 2when the latter is slid into slot 1, I provide a plate 0 'tact'i'ng withbushing 2 "so that it is only capable of pivotal movement about bush;

ingl. I I g The other end. .of theshade .is also piv-' otally mounted'asfclearly'shown in Figs. 4

and 5. For thispurpose. ahole 8 .is provided in the shade and-in opposedrelation.

thereto a hole 9 in thecbracket B." An. ad-

holes and is heldfin place byLwingnut 13. Suitable washers 11 and 12 offelt or other soft material or of resilient material are provided asshown in Fig. 5 for the purpose of protecting the. shade. i f

"In order to remove the shade it is necessary to remove screws 6 fromplate C or at least to turn them into such a positionthat they will notprevent removal of the shade from its seatin plate C. Next, the wing-nut13 is removedand screw 10 is slid out of engagement with the shade. Thelatter can now be liftedout of its place. and a new shade adjusted onthe lamp by performing the above operations in the reverse order.

Itwill be noted thatfthe electric wiring is in nowise disturbed by theremoval of the 100 shade. This is a great advantage with this type ofshade as the lamp socket isincon venient to reach and wiring it is atediousoperation.

My invention is particularly useful when 105 the advantageso'fbeinge101? @FFQYB: the 1m justing screw lOpasses freely through these shadewithout disturbing the wiring will be readily appreciated.

In Figs. 7 and 8 is shown a modification of my invention in whichtheshade is provided with a key-hole shaped opening consisting of a roundportion 1 and a slot 1, wide enough to pass over the parts of bracketsilient lower bent portion 7 is pivotallyhung from the bushing 2 andcarries in threaded engagement therewith two setscrews 6' which mayengage the projecting rim 3 of the shade B. The other end of the shadeis supported as before.

To remove the shade where this construction is employed, the same isfreed at one end by'removal of nut 13 (which ,,as has been stated, isretained in this modification). The screws 6 are then removed or turnedto such a position that the. resilient portion 7 of plate C may beremoved from engagement with the rim-3 of the shade, which is then slidto the right, as the parts are shown in Fig. 8, so that portions ofbracket B pass through the round portion I and slot 1? to effect acomplete disengagement of the shade from the lamp.

This modified construction differs from.

the form first described, in that the shade connot be removed. bylifting it away from its seat on bushing 2, as that is made impossibleby the narrow slot 1*, but must be slid in the direction of its length,as has been explained. i p 7 It is evident that my construction may haveother applications than the one disclosed herewith and it is understoodthat in my claims I do not limit myself to the exact disclosure of thedrawings and specification, but that said claims embrace all equivalentsto which I am by law entitled.

I claim: j
